5:19 p.m.: More than 14,000 firefighters battling California wildfires

Cal Fire has deployed over 2,400 engines, or 96% of its fleet, according to an announcement Monday. Over 14,000 firefighters are on the front lines. Yet Cal Fire is struggling to contain some of the larger blazes in the state.

The SCU Complex Fire, east of San Jose, is 10% contained, and the LNU Complex Fire, stretching from Napa to Yolo County is 22% contained. 

At a press conference Monday, Gov. Gavin Newsom pointed to climate change as the driver of this year’s destructive wildfire season.

“We are dealing with different climate conditions [resulting] in fires the likes of which we haven’t seen in modern recorded history,” he said. 

Evacuations have impacted more than 100,000 Californians, though some orders have started to lift. As the state shelters over 2,000 evacuees, coronavirus is a top concern. More than half are at “non-congregate” sites, such as hotels, to maintain social distancing.  

2:21 p.m.: Some LNU Complex evacuations could lift soon

More evacuation orders could soon be lifted in the massive LNU Lightning Complex fires burning in parts of Solano, Sonoma, Lake and Napa counties.

“From Winters south to Vacaville in the area along Pleasants Valley Road, there’s still a lot of heavy mop up, a lot of structure damage and we’re right now trying to get that area secure so we can start to move people in during the repopulation phase,” said Chris Waters, a Cal Fire operations section chief.

Thunderstorms are still predicted throughout the day, which has the potential for new fire starts.

More than 14,000 firefighters continue to battle wildfires around the state. There are two dozen major fires burning across the state and more than 600 individual fires in all — most of them in Northern California. The one closest to the Sacramento area — the LNU Lightning Complex Fire — is the second-largest wildfire in California history.  It has burned more than 350,00 acres and is 22% contained. 

Sonoma County officials are urging people affected by the fires  to reach out for emotional help if they’re feeling depressed. the county sheriff:

“This often time is a time when we start to feel a sense of loss as a community. That sinking feeling really starts to set in about what the loss is,” Sheriff Mark Essick said. “So we still encourage you to use those resources out there. The warmlines, you can call 211 for assistance if needed.”

“Warmlines” are phone numbers for people to call for mental health help. Meanwhile, Essick says officers are patrolling evacuated neighborhoods.

Sunday, August 23

3:20 p.m.: Lightning storms to start again Sunday evening

Dry lightning storms and strong winds could start in Northern California Sunday evening, according to meteorologists with Cal Fire.

The strikes will stretch from the Bay Area into the Central Valley and Sierra and have the potential to be similar to the siege that started the current rash of fires in the state.

Since August 15 more than 12,000 lightning strikes have started more than 615 fires. More than 1 million acres have burned in the state over that time.

A red flag warning is in effect for much of Northern California through Monday.

7:55 a.m.: Wildfires have burned more than 1 million acres in past week

The wildfires driven by last week’s lightning storms have now burned more than 1 million acres, according to the Associated Press.

The two main fires — The LNU and SCU lightning complexes — have combined burned more than 680,000 acres combined. The fires are the second and third largest in state history.

Firefighters are beginning to get help from other states, and Saturday President Donald Trump issued a major disaster declaration to provide federal assistance. But the state is now under a red flag warning as lightning storms are forecast to return Sunday and Monday

Saturday, August 22

3:25 p.m.: State Parks close near fire zones

California has fully or partially closed more than 30 state parks and recreation areas because of the many fires burning throughout the state.

Officials are recommending you avoid traveling to parks near fire areas, particularly in Santa Cruz, the Sonoma coast, Monterey and the Bay Area. State Parks is updating a list of closed parks here.

Camping reservation holders impacted by the wildfires are being contacted with cancellation information.

11:38 a.m.: Northern California could see more thunderstorms Sunday, while air quality expected to remain poor

California could get another round of lightning storms starting Sunday and extending until Tuesday, even as local health officials caution that unhealthy smoke from current fires could stay into next week.

The National Weather Service is forecasting dry thunderstorms that they want could produce lighting and fires. NWS has issued a fire weather watch starting Sunday at 11 a.m. and extending until 11 a.m. Tuesday for much of Northern California and the Bay Area.

Meanwhile, current fires could keep air quality in the Sacramento region poor until at least Tuesday, according to the Sacramento Metropolitan Air Quality Management District

While smoke levels are about half of what they were during the 2018 Camp Fire, levels are predicted to be unhealthy for sensitive groups (usually orange on air quality maps) Monday and Tuesday. It is likely that the highest pollution levels will occur during the afternoon, evening and early morning hours. Health officials recommend anyone who can stay indoors do so.

Cloth and surgical masks do not provide protection against smoke, but are still recommended if you have to go outside to protect against COVID-19. Here are some tips on what you can do if you must go outside.

The city of Sacramento is also transitioning two cooling centers to serve as clean air centers.

Tsakopoulos Library Galleria at 828 I St. and the Hagginwood Community Center at 3271 Marysville Blvd. will operate 10 a.m. to 8 p.m. daily. They will remain open until the smoke diminishes and the air quality improves.

Anyone using the centers will be required to wear a mask or face covering. If an individual does not have a mask, one will be provided for them.

In other news overnight, the Loyalton Fire in Sierra County has been declared over, and officials will not be providing further updates. The fire burned 47,028 acres. 

Friday, August 21

5:24 p.m.: Lightning Complex fires some of the largest in state history

The SCU Lightning Complex burning around Santa Clara County and the LNU Lightning Complex fires in Napa and Solano counties are now both in the top-10 largest recorded fires ever in California.

The SCU Lightning fires — which have caused evacuations into Stanislaus and San Joaquin counties — have now burned 229,968 acres and are the seventh-largest fire on record. The LNU Lightning fires have burned 219,067 acres, the 10th-largest fire, according to Cal Fire.

Further lightning storms are possible from Sunday to Tuesday throughout Northern California, prompting a fire weather watch for the region.

2:18 p.m.: California wildfires have torched roughly the size of Rhode Island

Firefighters across California are battling blazes that have now torched more than 771,000 acres, which is roughly the area of the state of Rhode Island.

The fires have killed at least five people and stretched the state’s firefighting resources thin. California will receive some aid through the Federal Emergency Management Agency, and Western states are sending additional resources, but officials worry it may not be enough.

Gov. Gavin Newsom tweeted Friday that there have been more than 560 fires since the current situation began, with 18 new fires since yesterday.

9:20 a.m.: Man who lived on Pleasant Valley Road in Solano County died in LNU Lightning fires

One of the four people who has died in the LNU Lightning Complex fires was a man who lived on Pleasant Valley Road in Solano County, the Solano County Sheriff’s Department reports.

Sheriff Tom Ferrara said Thursday that the English Hills area and Pleasant Valley Road in North Solano County is where he anticipates there will be the most damage from the fires. 

While the fire is still actively growing, Solano County Sheriff’s Lt. Jackson Harris said Friday morning in a Facebook Live that crews have achieved a little bit of containment in Solano County, about 1%. 

Harris stressed that containment does not mean 100% safety, but said the Sheriff’s Department is in talks with Cal Fire to start repopulating portions of the county.

8:05 a.m.: Crews make progress in Loyalton Fire Thursday

The Loyalton Fire in Sierra County is now 60% contained and has burned 46,872 acres.

Largely the result of an unprecedented lightning siege with nearly 11,000 strikes over several days, there are more than two dozen major fires scorching California.

Fire officials say that hundreds of thousands of acres have burned, and that competition is tight for resources with so many fires. That has led Cal Fire and the California Office of Emergency Services to ask for support from other states and the federal government.

Due to the wildfire crisis, California Gov. Gavin Newsom is no longer slated to speak during a primetime slot at tonight’s Democratic National Convention.

Statewide, the fires have destroyed 175 homes and other buildings and are threatening 50,000 more. Officials say 33 civilians and firefighters have been injured.
